    FIGURE 1. Two monolithic beam expansion systems are shown with spherical surfaces (top) and with a convex aspheric surface (center) for an enlargement of M=2. Incoming beam diameter is 10 mm. The wavefront aberrations for the aspheric approach are four orders of magnitude smaller. Three cascade systems are shown for beam expansion based on monolithic individual systems (bottom: 10.5x enlargement (a), 21x enlargement (b), and 9.3x enlargement (c). System (b) differs from (a) by the addition of an element with M=2. System (c) differs from (b) by the inversion of the last element with M=1.5.
    This year's Tech Review Top 20 list concludes with an especially robust selection of science topics from the past year of Laser Focus World.
    FIGURE 2. A cascade of five beam expanders with M=21 and a design wavelength of 532 nm is used at a 600 nm wavelength (top). The wavefront, divergence, P-V, and RMS of the wavefronts after passing through the given number of beam expanders are compared (bottom).
    Single-element beam expanders containing an aspheric surface can be used in cascade to create different magnifications; an added lens adjusts for wavelength-change effects.
